In this article, I will explain “intervertebral discs” in detail.
The intervertebral disc is located between the spine and acts as a cushion so that the body can move smoothly. However, since it is soft, it is easy to damage, and it often causes problems such as a herniated disc. There is a part called the nucleus (nuclear medulla) at the center of the intervertebral disc, and this part absorbs and distributes pressure well. However, as we age or continue to have a bad posture, the function of the nuclear medulla declines, and the risk of intervertebral discs being deformed or herniated increases. Therefore, proper posture and exercise are needed to keep the intervertebral discs and nuclear medulla healthy.

What is an intervertebral disc
An intervertebral disc is a cushion-like tissue that exists between the vertebrae. This tissue is made up of cartilage and is extremely flexible. If your spine is made only of hard bones, you won't be able to move flexibly, but thanks to intervertebral discs, you can freely move your body left, right, back and forth.
How to read intervertebral discs
The correct way to read intervertebral disc is “hard bang.”
Characteristics of intervertebral discs
Intervertebral discs are characterized by extremely high flexibility. However, behind its high flexibility, there is also an aspect where it cannot withstand the weight and is easily damaged. Therefore, there are risks such as herniated discs.
Location and position of intervertebral discs
The intervertebral disc is located between the vertebrae from the neck to the lower back. They are arranged across the cervical, thoracic, and lumbar vertebrae, and act as flexible cushions between bones.
How to remember intervertebral discs
Remember it as “a soft cushion between vertebrae.” This image shows the location and characteristics of intervertebral discs.
English and Latin for intervertebral discs
Intervertebral discs are expressed as “intervertebral discs” in English, and “discus intervertebralis” in Latin. It contains the meaning of “a disc between the bones of the spine.”
Trivia about intervertebral discs
Correct posture is extremely important in order not to damage intervertebral discs. Protect your intervertebral discs and keep them healthy in your daily life, such as proper exercise and proper lifting methods.
Tissues associated with intervertebral discs: nuclear features
The nucleus at the center of the intervertebral disc is officially called the “nuclear medulla,” and is mainly composed of water and proteoglycans. This nuclear medulla is a jelly-like substance and has the role of absorbing and dispersing pressure applied between vertebrae. The healthier the nuclear medulla, the more the intervertebral disc can maximize its cushioning function and maintain the flexibility and stability of the spine. However, as water in the nuclear medulla decreases due to aging, excessive use, improper posture, etc., and changes in the structure of proteoglycans, nuclear function declines. This can also cause intervertebral disc degeneration and hernias, so it can be said that the health of the nuclear medulla is directly linked to the health of the entire spine.
Tissues associated with intervertebral discs: location and location of the nucleus
The nuclear medulla is located in the center of the intervertebral disc, and is surrounded by fibrous tissue called the fibrous ring. This fiber ring has the role of preventing the nuclear medulla from flowing outward when exposed to excessive pressure. The intervertebral disc itself is present in every part that forms the spine, that is, from the neck to the chest, lower back, and sacrum.
The location of the nuclear medulla is in the center of the intervertebral disc when the disc is healthy, but when the intervertebral disc is deformed or the pressure is skewed to one side, the nucleus is unbalanced, and eventually breaks through the fibrous ring, causing a herniated disc.
Tissues associated with intervertebral discs: nuclear trivia
Nuclear medulla has the highest water content at birth, and its water content decreases as we age. This is one of the main reasons for disc deformity due to aging. Furthermore, the water content of the nuclear medulla fluctuates throughout the day. While awake and active, pressure is applied to the intervertebral discs, which gradually pushes water out. This causes your height to shrink slightly during the day. Conversely, when lying down and resting, the nuclear medulla will absorb water again and your height will be restored.
